8 Claims. (Cl. 16-140) This invention relates to an improved hinged device,

and more particularly to an improved leaf hinged check device having adjustable means for frictionally holding a swinging member, such as a door, in any desired position.

In certain instances, it is desirable to provide a means for reliably maintaining swinging members, such as doors,

in a desired open position, or to provide a means for preventing their inadvertent slamming because of winds,-

drafts, or other causes. As most existing door and frame constructions are adapted to employ conventional leaf type hinges, the pri mary object of this invention is to provide an improved' hinged check device which is easily used in place of a con-- ventional leaf hinge or installed in addition thereto.

Another object of this invention is to provide an improved leaf hinged check device having means inherent in the device itself for frictionally holding the device a predetermined angular position.

Another object of this invention is to provide an improved leaf hinged check device having a means for ad-' justing the bearing friction between the moving parts of the hinge.

Another object of this invention is to provide an improven hinged check device having means for varyingits frictional resistance when in position. V

- 'A still further object of this invention is to provide an improved frictionally adjustable leaf hinged check'de vice which is adaptable to replace an existing hinge assembly.

A still further object of this invention is to provide an improved frictionally adjustable leaf hinged check device which can be easily installed on existing door frame assemblies. 1

A still further objection of this invention is to provide an improved frictionally adjustable leaf hinged check de-' vice which is simple in its construction, and reliable and 7 effective in its operation.

.Other objects, purposes, and characteristic features of" this invention will be apparent from the accompanying drawings, the-specifications, and the recital of the .ap -j pended claims. In the drawings:

V Fig. 9 is a perspective view of a portion of tion' of the journal with the rod removed.

The'embodiment of the invention shown in Figs. 1 I through 4 is adaptable to replace the conventional leaf engage and axially align with the journals 13 of the:

' leaf 10.

Each of the journals 14 is transversely split by an elongated cut or slit 15 which extends into the flat portion of the leaf 11. The leaf 11 is also provided with two sub- -stanti,ally parallel elongated slits 16 which extend into the flat portion of the leaf 11 on the same lines or planes as the edges of the journals 14. The elongated slits 15 and 16 provide flexibility and lateral deflectability to the intermediate portions of the journals 14. In accordance" with the size of the hinged device, the flat portion of the leaf 11 may be formed with elliptical depressions 50 on its underside to render a greater flexibility to the journals 14.

Frictionally mounted in the journals 13 and 14' of the leaves 10 and 11 is a fibrous tubular-rod or sleeve 17.

receive the pressurebar 20 when the hinge is in a closed i position. This arrangement permits the surfaces of the 7 leaves '10 and-11 to lay flat in relation to each other,"

The sleeve 17 engages and surrounds a rod or hinge pin 18. Connected to the upper end of the fiber sleeve 17 are pins '23 which rest in slots 24 formed in the outer edge of the journal 13 of the leaf 10, and are provided to prevent-rotation of the rod or sleeve 17 relative to thejournal l3. Each end of the hinge pin 18 is adaptable to threadably receive a retaining nut 19. The retaining nuts 19 may be knurled or otherwise configurated to permit easy assembly or disassembly.

An elongated pressure bar 20, which is substantially the same thickness as the leaf 10, is threadably and adjustably secured to the flat portion of the leaf 11 across the slits 15 and 16 and alongside the journals 14 by adjusting screws 21.

The-pressure bar is provided with rivets or studs 22 which'are adapted to engage the flexible surface of the leaf-11 between each pair of slits 15 and 16 respectively."

The tightening of the adjusting screws 21 creates a ten- 7 sion on the outer sections of journals 14 and a pressure on the inner flexible portions'of the journals 14 thereby, tending to cause ,a lateral flexing of the leaf 11 and'an axial-misalignment of the journalsld, which increases thefrictional resistance of the hinge pin 18 and the sleeve 17 in the journal 14..

The leaf 10 has-an elongated opening 25 adaptableto thereby permitting a door D, for example, onv which it isused, to be completely closed. Although Fig. 5 shows the door D and the door frame F not quite closed, it is apparent that the hinge leaves 10 and 11 are adapted to bear against each other in the closed position.

The modified form of the invention shown in .Fig. 6

through 9; is intended to be used in addition to the existing hinges already provided in a door, although it may;

existing hinges in light weight door'i be used inplace of and frame assembly. it:

Patented Niar. 29, 1960 the modified leaf hinged check device showing the misaligned posi-- inner'end' of the plate 39 is rigidly attached by a rivet 32 in a slot 34'which is provided in the upper end of a rod or hinge pin 33. The rod 33 is normally mounted in a plurality of axially aligned journals 41, 42, 43, 44, and 45; which are integrally formed in-' a leaf hinge member 37. Journals 41 and 45 are-theouter journals,-

The journal' portions 4'l through 4S-and the bushings 35 are separatedbyelongated snb stantially parallel slits 38' which extend' into the: flat portion of the hinge leaf 37. The leaf 37 isadapted to be attached to a door byconventional screws inserted" through the countersunk-openings 36'.

Thus, I have provided an improvedleaf hinge,- and leaf hinged check device, one embodiment which is intended to replace the conventional leaf hinges now in operation, and the other embodiment is intended to sup" plement and be used in addition to the leaf hinges already. installed where it seems undesirable to removethe present conventional type hinge.
